Upgrading ISA Server 2000 Dial-up, Chaining, and Routing Configuration
Most ISA Server 2000 dial-up, chaining, and routing configuration settings are upgraded to ISA Server 2004, as detailed in the following sections.
Dial-up Connections
In ISA Server 2000, multiple dial-up connections could be created, but only one dial-up connection could be active at a time. In ISA Server 2004, only a single dial-up can be created.
In ISA Server 2000, the dial-up connection was defined per Firewall Client and per Web Proxy client. In ISA Server 2004, the dial-up connection is defined per network.
As part of the upgrade process, only the active dial-up connection is upgraded. It is assigned to the External network.
All other dial-up connections are not upgraded. This is noted in the upgrade log file.
Firewall Chaining
ISA Server 2000 chaining configuration is upgraded directly to ISA Server 2004. The only exception is the dial-up connection specified on ISA Server 2000. On ISA Server 2004, the dial-up connection is created on the External network.
Routing Rules
Each ISA Server 2000 routing rule is duplicated on ISA Server 2004, as a cache rule and as a routing rule.
The ISA Server 2004 routing rule is created with identical properties to those of the original ISA Server 2000 routing rule. The destinations specified for the ISA Server 2000 routing rule are mapped to specific networks on the To property page of the ISA Server 2004 routing rule properties. For specific details, see Destination Sets and Rules.
If the ISA Server 2000 routing rule used a dial-up entry, then a dial-up entry with the same properties is created on the External network of ISA Server 2004.
A new caching rule is created based on the original ISA Server 2000 routing rule. The destinations specified for the ISA Server 2000 routing rule are mapped to specific networks on the To property page of the ISA Server 2004 routing rule properties. For specific details, see Destination Sets and Rules.
The following properties are not supported on ISA Server 2004 caching rules and are therefore not upgraded from the original ISA Server 2000 routing rule: bridging and action.
